Actually, I don't know jack about fishing, so I might not be using the right term. I'm thinking of that cable-like stuff. But then I've also bought music wire like thin rods at fishing shops too. I'll be using the cable stuff.

PS. Not knowing jack about fishing didn't stop me from catching a 1.5m sailfish with just a block of foam wrapped with line off the coast of Oman or from snagging 3 enormous, fat trout the very first time I ever cast with a fly rod (no bait needed) in Kamchatka!
